The work is devoted to investigation of stable color centers (CC) that are created in Gd 3 Ga 5 O 12 (GGG) crystals under irradiation with γ-quanta (E=1.25 MeV, D= 10 5 Gy ) as well as transient CC created in the crystals under irradiation with pulsed electron beam (E=0.25 MeV, pulse duration 10 ns, fluence 10 12 cm -2 , time interval of registration 0-500 ns). On the basis of the performed study of optical absorption spectra of the as-grown and irradiated crystals it was established the correlation between a defect subsystem of as-grown crystals and a type of CC induced by radiation in the crystals. The role of Ca 2+ dopant ions in the processes of CC formation is examined. Models of the stable and transient CC are proposed.

“…Literature on radiation tests of Er-doped garnet crystals report a significant effect of gamma radiation on transmission in the visible range and on laser properties of a flashlamp-pumped laser at a wavelength of 2.94 µm. Gamma irradiation with a dose in the krad-range significantly increases the output energy of a flashlamp-pumped laser, because induced color centers augment the absorption of the spectrally broad pump light [8]. Systematic studies of radiation effects on laser crystals with a space-application scenario have been reported for Nd-doped YAG and YLF crystals.…”

A test campaign for assessing the radiation hardness of different Erbium-doped garnet crystals including Er:YAG and a compositionally tuned Er:YAG/Er:LuAG mixed garnet is reported. Tests with proton and gamma radiation have been performed with parameters mimicking a 3-year low-earth-orbit satellite mission like MERLIN or ADM-Aeolus. For each test sample broadband transmission spectra in the wavelength range of 500 nm -1700 nm and characteristic laser curves from a test laser oscillator have been measured. Radiation-induced losses have been calculated from the obtained data. The results indicate that gamma radiation is the dominant loss source with about 0.5 %/cm radiation-induced losses for the nominal dose of the chosen mission scenario
